Definitions
- the present invention relates to the maintenance of a jet engine, and particularly to a nozzle for cooling a jet engine for maintenance.
- the present invention further concerns an apparatus for cooling a jet engine for maintenance and a method for maintenance of a jet engine.
- the jet engine can be cooled by sucking air from the exhaust channel of the jet engine with a suction pipe arranged to the exhaust channel.
- This can be made more effective by sealing the remainder of the exhaust channel for example with a plastic film and tape. Installing the sealing is, however, time consuming and difficult.
- Publications CN 106494639 A and CN 104691777 A disclose arrangements for cooling aircraft engines.
- Publications US 2011/0232697 A1 , WO 2008/025940 A1 and U.S. Patent no. 5,899,217 disclose arrangements for recovering waste water from clearing operations performed on aircraft engines.
- An object of the present disclosure is to provide a nozzle, an apparatus comprising the nozzle and a method utilizing the apparatus so as to overcome the above problems.
- the object of the disclosure is achieved by a nozzle, an apparatus comprising the nozzle and a method utilizing the apparatus which are characterized by what is stated in the independent claims.
- the preferred embodiments of the disclosure are disclosed in the dependent claims.
- the disclosure is based on the idea of providing a nozzle for cooling a jet engine for maintenance, wherein the nozzle comprises a suction adapter having a round shape adapted to be connected in sealed manner to the exhaust channel of a jet engine for sucking air from the exhaust channel, and a suction channel in fluid connection with the suction adapter for sucking air from the suction adapter, wherein the suction channel is arranged to be connected to an air suction device.
- An advantage of the nozzle of the disclosure is that it allows quick attachment to the exhaust of a jet engine without the need for manual seal fixing and taping and thus the cooling can be initiated quickly after the jet engine is received to the maintenance.
- the invention relates to a nozzle 12 for cooling a jet engine 2 for maintenance.
- the jet engine 2 is a turbojet engine, a turbofan engine or a turboprop engine.
- the jet engine 2 comprises an exhaust channel 21 for the exit of exhaust gases of the jet engine 2. These hot exhaust gases are utilized to produce thrust.
- the exhaust channel 21 may be formed by a passage between an exhaust pipe, or an exhaust case, and an exhaust cone arranged coaxially at the rear portion of the jet engine 2.
- the exhaust channel 21 may be formed solely by the exhaust pipe.
- the exhaust pipe extends longitudinally beyond the exhaust cone and thus the end of the exhaust channel 21, or an exhaust nozzle, is formed solely by the exhaust pipe.
- the nozzle 12 comprises a suction adapter 121.
- the suction adapter 121 is adapted to be connected in sealed manner to the exhaust channel 21 of the jet engine 2 for sucking air from the exhaust channel 21 for cooling the jet engine 2.
- the connection in sealed manner means that essentially no air is leaked between the exhaust channel 21 and the suction adapter 121.
- Connection between the suction adapter 121 and the exhaust channel 21 is illustrated in Figure 2 .
- the suction adapter 121 comprises elastic material for forming a seal with the exhaust channel 21.
- the suction adapter is 121 is made of rigid material, such as plastic.
- the suction adapter 121 comprises at least one rim 121a, and the rim 121a is provided with an elastic seal.
- the suction adapter 121 itself can be made essentially of elastic material, such as silicone rubber, and it is optionally provided with a rigid support structure for supporting the elastic part of the suction adapter 121.
- the nozzle 12 comprises a suction channel 122.
- the suction channel 122 is in fluid connection with the suction adapter 121 for sucking air from the suction adapter 121.
- the suction channel 122 is arranged to be connected to an air suction device 13.
- the suction adapter 121 has a round shape.
- the round shape facilitates the connection to the exhaust channel 21 having a corresponding round shape.
- the suction adapter 121 has a conical shape.
- the suction adapter 121 comprises one rim 121a formed at the annular periphery of the conical shape.
- the conical-shaped suction adapter 121 is suitable for jet engines in which the exhaust channel is formed by an exhaust pipe and an exhaust cone, and jet engines in which the exhaust channel, or at least the exhaust nozzle, is formed solely by exhaust pipe.
- the conical suction adapter 121 is fitted to the exhaust of the jet engine 2 so that the rim 121a comes in contact with the exhaust pipe or the exhaust nozzle.
- a conical-shaped suction adapter 121 is illustrated in Figures 1 and 2 .
- the suction adapter 121 has an annular shape having a U-shaped cross-section for forming a semi-open annular channel, and the suction channel 122 is connected to the periphery of the semi-open annular channel of the annular suction adapter 121.
- the suction adapter 121 comprises two rims 121a formed at the inner periphery and the outer periphery of the semi-open annular channel.
- the annular suction adapter 121 is suitable for jet engines in which the exhaust channel is formed by an exhaust pipe and an exhaust cone.
- annular suction adapter 121 When the nozzle 12 is used, the annular suction adapter 121 is fitted between the exhaust pipe and the exhaust cone so that the inner rim 121a comes in contact with the exhaust cone and the outer rim 121a comes in contact with the exhaust pipe.
- An annular-shaped suction adapter 121 is illustrated in Figure 3 .
- the invention relates also to an apparatus 1 for cooling a jet engine 2 for maintenance.
- the apparatus 1 comprises a frame 11 arranged to support the apparatus 1 movably on the ground.
- the frame 11 has been provided with wheels at the bottom of the frame.
- the apparatus 1 comprises a nozzle 12 as described above.
- the nozzle 12 is supported by the frame 11.
- the frame 11 comprises at least one support arm 111 and the nozzle 12 is supported by the support arm 111.
- the nozzle 12 is arranged detachably to the apparatus 1. This allows selecting and replacing the nozzle 12 according to the type of the jet engine in question.
- the frame 11 comprises location adjustment means for adjusting the vertical location of the nozzle 12 in relation to the frame 11.
- the location adjustment means are arranged at the support arm 111.
- the support arm 111 has a telescopic structure for modifying its length. The purpose of the location adjustment means is to allow using the apparatus 1 for cooling jet engines 2 of airplanes having the jet engines 2 at different heights from the ground.
- the apparatus 1 comprises an air suction device 13 connected to the nozzle 12 for sucking air from the nozzle 12.
- the air suction device 13 is a suction fan.
- the air suction device 13 is also able to blow air to the nozzle 12.
- the invention relates also to a method for maintenance of a jet engine 2.
- the method comprises providing a jet engine 2 comprising an exhaust channel 21 for the exit of exhaust gases of the jet engine 2.
- the jet engine 2 has heated during use of the jet engine 2.
- the nozzle 12 of an apparatus 1 as described above is connected to the exhaust channel 21. Then air is sucked from the exhaust channel 21 with the apparatus 1 for cooling the jet engine 2. Then maintenance operations are performed to the cooled jet engine 2.
- the jet engine 2 comprises an air inlet 22 that is in fluid connection with the exhaust channel 21.
- the method comprises feeding cooled air to the air inlet 22.
- the cooled air flows from the air inlet 22 through the jet engine 2 to the exhaust channel 21 and onwards to the apparatus 1.
- Cooled air relates to air that is cooler than ambient air. Feeding cooled air to the inlet 22 makes the cooling of the jet engine 2 more efficient.
